[0001] The present invention relates to the technical field of crushing devices, and specifically to a crushing device and a production method for silicon carbide sand. Background Art

[0002] Silicon carbide sand is an artificially synthesized inorganic non-metallic material, mainly composed of silicon carbide. Due to its high hardness, high temperature resistance, and excellent physical and chemical properties, it is widely used in the industrial field.

[0003] Chinese Patent CN115283061B discloses a silicon carbide ultrafine powder preparation device, including a mounting base and a flipping platform frame hinged on the upper surface of the mounting base near the edge. The top of the flipping platform frame is fixed with a mounting platform. The top of the mounting platform is fixed with a splash-proof guard cylinder near the circumferential edge, and a circular hole is opened in the middle of the mounting platform.

[0004] In the above patent and the prior art, when the crushing device crushes silicon carbide, due to the high hardness of silicon carbide, silicon carbide particles are prone to splash everywhere inside the crushing chamber, and the splashed silicon carbide is easily mixed into the crushed silicon carbide sand, thus affecting the overall quality of the silicon carbide sand. Summary of the Invention

The silicon carbide guide plate inside the silicon carbide crushing chamber can further guide silicon carbide into the inside of the crushing mechanism. The driving mechanism can drive the crushing mechanism to crush silicon carbide through the transmission mechanism. The silicon carbide filtering mechanism can filter the silicon carbide sand. When the crushing mechanism crushes silicon carbide, it can also drive the silicon carbide recovery mechanism to move the incompletely crushed silicon carbide above the crushing mechanism for further crushing.

[0007] Preferably, the crushing mechanism includes a first rotating rod and a second rotating rod.

When the first rotating rod rotates forward, it can drive the second rotating rod to rotate in the reverse direction through the meshing connection between the first rotating rod gear outside and the second rotating rod gear outside the second rotating rod. When the first rotating rod and the second rotating rod rotate, they can respectively drive the first crushing roller and the second crushing roller to rotate, and the rotation of the first crushing roller and the second crushing roller can crush the silicon carbide.

[0009] Preferably, a transmission bin and a recovery bin are separately opened inside the silicon carbide crushing bin. The connection part between the first rotating rod gear and the second rotating rod gear is located outside the silicon carbide crushing bin. The second rotating rod is in transmission connection with the silicon carbide recovery mechanism through the recovery transmission gear, and the connection part between the second rotating rod and the recovery transmission gear is located inside the transmission bin; When the second rotating rod rotates, it can drive the silicon carbide recovery mechanism through the recovery transmission gear to move the incompletely crushed silicon carbide above the silicon carbide guide plate.

[0010] Preferably, the silicon carbide recovery mechanism includes a recovery main body rotating rod and a lower recovery rotating wheel. The lower recovery rotating wheel is installed inside the recovery bin, the recovery main body rotating rod is installed inside the silicon carbide crushing bin, a uniform feeding cylinder is arranged outside the recovery main body rotating rod, an upper recovery rotating wheel is installed outside the recovery main body rotating rod, a recovery transmission belt is installed outside the upper recovery rotating wheel, a silicon carbide recovery box is installed outside the recovery transmission belt, and a recovery rotating rod gear is installed outside the recovery main body rotating rod.

[0011] Preferably, the connection part between the recovery main body rotating rod and the recovery rotating rod gear is located inside the transmission bin. The outside of the recovery main body rotating rod is in transmission connection with the second rotating rod through the recovery rotating rod gear, and the number of teeth on the outside of the recovery rotating rod gear is more than the number of teeth on the outside of the recovery transmission gear; When the second rotating rod rotates, it can drive the main body recovery rod to rotate through the meshing connection between the recovery transmission gear and the recovery rod gear. The difference in the number of teeth on the recovery transmission gear and the number of teeth on the recovery rod gear enables the main body recovery rod to rotate one week after the second rotating rod rotates multiple weeks. When the main body recovery rod rotates, it can drive the uniform feeding cylinder and the upper recovery rotating wheel to rotate. When the uniform feeding cylinder rotates, it can uniformly feed silicon carbide.

[0012] Preferably, the outside of the upper recovery rotating wheel is drivingly connected to the lower recovery rotating wheel through a recovery transmission belt, and the silicon carbide recovery boxes are evenly distributed outside the recovery transmission belt; When the main body recovery rod drives the upper recovery rotating wheel to rotate, it can drive the lower recovery rotating wheel and the recovery transmission belt to rotate. When the recovery transmission belt rotates, it can drive the external silicon carbide recovery boxes to move synchronously.

[0013] Preferably, one side of the silicon carbide recovery box that fits with the recovery bin is provided with an opening, and one side of the silicon carbide recovery box facing the rotation direction of the recovery transmission belt is provided with an opening; When the recovery transmission belt drives the silicon carbide recovery box to move, the silicon carbide recovery box can collect the silicon carbide with larger particles and drive it to rise.

[0014] Preferably, the inside of the silicon carbide filtering mechanism is lower on the side close to the recovery bin than on the side far from the recovery bin, and there are two openings and a collection groove inside the recovery bin; The silicon carbide with larger particles on the silicon carbide filtering mechanism can enter the collection groove inside the recovery bin through the opening at the lower part of the recovery bin.

[0015] A production method for silicon carbide sand uses the above-mentioned crushing device.

[0016] Compared with the prior art, the present invention provides a crushing device and a production method for silicon carbide sand, having the following beneficial effects: 1. For this crushing device, when the first rotating rod rotates forward, it can drive the first crushing roller to rotate forward synchronously. When the first rotating rod rotates, it can also drive the second rotating rod to rotate reversely inside the silicon carbide crushing bin through the meshing of the external first rod gear and the second rod gear outside the second rotating rod. When the first crushing roller rotates forward, the second crushing roller rotates reversely, and the two jointly crush the silicon carbide. Moreover, when the second rotating rod rotates, it can also drive the silicon carbide recovery mechanism to recover the silicon carbide particles and crush them again through the recovery transmission gear, thereby preventing the silicon carbide particles that are not completely crushed from being mixed into the silicon carbide sand.

[0017] 2. When the second rotating rod rotates, the external recovery drive gear can drive the recovery main rod to rotate through the engagement with the recovery rod gear outside the recovery main rod. The number of teeth on the recovery rod gear is more than that on the recovery drive gear, so that the recovery drive gear can only drive the recovery rod gear to rotate one week when it rotates multiple weeks. When the recovery main rod rotates, it can drive the uniform feeding cylinder to rotate. When the uniform feeding cylinder rotates, it can uniformly feed the silicon carbide guided by the silicon carbide deflector, preventing the silicon carbide from blocking the outlet at the bottom of the silicon carbide deflector.

[0018] 3. When the crushing mechanism crushes the silicon carbide incompletely or the splashed silicon carbide particles enter the collection tank inside the recovery bin from the opening at the lower part of the recovery bin under the filtration and guidance of the silicon carbide filtration mechanism. When the recovery drive belt drives the silicon carbide recovery box to move, the silicon carbide recovery box can collect the silicon carbide particles in the collection tank and drive the silicon carbide particles to move above the silicon carbide deflector when the silicon carbide recovery box moves. After the silicon carbide particles enter above the silicon carbide deflector, they can enter the crushing mechanism again for secondary crushing, thus significantly improving the crushing quality of the silicon carbide particles.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a crushing device and a production method for silicon carbide sand.

[0023] Embodiment 1: Please refer to Figure 1 - Figure 10 , a crushing device, including a crushing installation platform 1, a driving mechanism 2 is installed on the top of the crushing installation platform 1, the driving end of the driving mechanism 2 is connected to a transmission mechanism 3, the other end of the transmission mechanism 3 is connected to a crushing mechanism 4, a silicon carbide crushing bin 5 is installed on the top of the crushing installation platform 1, a silicon carbide recycling mechanism 6 is installed inside the silicon carbide crushing bin 5, a silicon carbide feeding port 7 is installed on the top of the silicon carbide crushing bin 5, a silicon carbide deflector 8 is installed inside the silicon carbide crushing bin 5, a silicon carbide filtering mechanism 9 is installed inside the silicon carbide crushing bin 5, and the bottom of the silicon carbide crushing bin 5 is connected to a discharge port 10; The crushing mechanism 4 is installed inside the silicon carbide crushing bin 5, the outside of the crushing mechanism 4 is in transmission connection with the driving mechanism 2 through the transmission mechanism 3, and the crushing mechanism 4 is in transmission connection with the silicon carbide recycling mechanism 6 inside the silicon carbide crushing bin 5; The silicon carbide feed inlet 7 can guide silicon carbide into the interior of the silicon carbide crushing bin 5. The silicon carbide deflector plate 8 inside the silicon carbide crushing bin 5 can further guide the silicon carbide into the interior of the crushing mechanism 4. The driving mechanism 2 can drive the crushing mechanism 4 through the transmission mechanism 3 to crush the silicon carbide. The silicon carbide filtering mechanism 9 can filter the silicon carbide sand. When the crushing mechanism 4 crushes the silicon carbide, it can also drive the silicon carbide recycling mechanism 6 to move the incompletely crushed silicon carbide above the crushing mechanism 4 for further crushing.

[0024] During operation, first start the driving mechanism 2. Drive the crushing mechanism 4 to start the crushing work through the driving mechanism 2. Then add silicon carbide into the interior of the silicon carbide crushing bin 5 through the silicon carbide feed inlet 7. The silicon carbide added into the interior of the silicon carbide crushing bin 5 moves towards the middle of the crushing mechanism 4 under the guidance of the silicon carbide deflector plate 8. Driven by the driving mechanism 2, the crushing mechanism 4 can crush the silicon carbide. When the crushing mechanism 4 crushes the silicon carbide, it can also drive the silicon carbide recycling mechanism 6 to evenly feed the silicon carbide. The crushed silicon carbide is discharged from the discharge port 10 after being filtered by the silicon carbide filtering mechanism 9. When the silicon carbide filtering mechanism 9 filters the silicon carbide, it can also guide the larger silicon carbide particles into the interior of the recycling bin 12. Driven by the crushing mechanism 4, the silicon carbide recycling mechanism 6 can move the silicon carbide particles above the silicon carbide deflector plate 8 and re-enter the interior of the crushing mechanism 4 for crushing. When the crushing mechanism 4 crushes the silicon carbide, the inclined structure of the silicon carbide filtering mechanism 9 collects the incompletely crushed large-particle silicon carbide, and after collection, drives the silicon carbide particles to rise through the silicon carbide recycling mechanism 6 for secondary crushing, thereby effectively preventing incompletely crushed silicon carbide particles from mixing into the silicon carbide sand and affecting the overall quality of the silicon carbide sand.

[0025] Embodiment 2: The difference from the above embodiment is as follows. Please refer to Figure 1 - Figure 10 The crushing mechanism 4 includes a first rotating rod 41 and a second rotating rod 44. The first rotating rod 41 is installed inside the silicon carbide crushing bin 5, and the second rotating rod 44 is installed inside the silicon carbide crushing bin 5. A first rotating rod gear 42 is installed outside the first rotating rod 41, a first crushing roller 43 is installed outside the first rotating rod 41, a second rotating rod gear 45 is installed outside the second rotating rod 44, a second crushing roller 46 is installed outside the second rotating rod 44, and a recycling transmission gear 47 is installed outside the second rotating rod 44.

[0026] One end of the first rotating rod 41 is in transmission connection with the driving mechanism 2 through the transmission mechanism 3. The first rotating rod gear 42 outside the first rotating rod 41 is meshed and connected with the second rotating rod gear 45 outside the second rotating rod 44. The driving mechanism 2 can drive the first rotating rod 41 to rotate through the transmission mechanism 3. When the first rotating rod 41 rotates forward, it can drive the second rotating rod 44 to rotate reversely through the meshing connection between the external first rotating rod gear 42 and the external second rotating rod gear 45 of the second rotating rod 44. When the first rotating rod 41 and the second rotating rod 44 rotate, they can respectively drive the first crushing roller 43 and the second crushing roller 46 to rotate. The rotation of the first crushing roller 43 and the second crushing roller 46 can crush silicon carbide.

[0027] A transmission chamber 11 and a recovery chamber 12 are separately provided inside the silicon carbide crushing chamber 5. The connection between the first rotating rod gear 42 and the second rotating rod gear 45 is located outside the silicon carbide crushing chamber 5. The outside of the second rotating rod 44 is connected to the silicon carbide recovery mechanism 6 through the recovery transmission gear 47. The connection between the second rotating rod 44 and the recovery transmission gear 47 is located inside the transmission chamber 11. When the second rotating rod 44 rotates, it can drive the silicon carbide recovery mechanism 6 to move the incompletely crushed silicon carbide to the top of the silicon carbide guide plate 8 through the recovery transmission gear 47 .

[0028] When working, the driving mechanism 2 can drive the first rotating rod 41 to rotate forwardly inside the silicon carbide crushing bin 5 through the transmission mechanism 3. When the first rotating rod 41 rotates forwardly, it can drive the first crushing roller 43 to rotate forward synchronously. When the first rotating rod 41 rotates, the first rotating rod gear 42 outside the first rotating rod 44 can be meshed with the second rotating rod gear 45 outside the second rotating rod 44 to drive the second rotating rod 44 to rotate reversely inside the silicon carbide crushing bin 5. When the second rotating rod 44 rotates reversely, it can drive the second crushing roller 46 to rotate reversely synchronously. When the first crushing roller 43 rotates forward, the second crushing roller 46 can rotate reversely. The crushing rollers 46 rotate in opposite directions and together crush the silicon carbide. The crushed silicon carbide sand falls downward and is discharged from the discharge port 10 after being filtered by the silicon carbide filtering mechanism 9. When the first crushing roller 43 and the second crushing roller 46 are crushing the silicon carbide, the silicon carbide filtering mechanism 9 can also guide the incompletely crushed silicon carbide particles to the inside of the recovery bin 12, and when the second rotating rod 44 rotates, it can also drive the silicon carbide recovery mechanism 6 to recover the silicon carbide particles and crush them again through the recovery transmission gear 47, thereby preventing the incompletely crushed silicon carbide particles from being mixed into the silicon carbide sand.

[0029] Embodiment three: The difference from the above embodiment is that, please refer to Figure 1 - Figure 10, the silicon carbide recycling mechanism 6 includes a recycling main body rotating rod 61 and a lower recycling rotating wheel 64. The lower recycling rotating wheel 64 is installed inside the recycling bin 12, and the recycling main body rotating rod 61 is installed inside the silicon carbide crushing bin 5. A uniform feeding cylinder 62 is arranged outside the recycling main body rotating rod 61. An upper recycling rotating wheel 63 is installed outside the recycling main body rotating rod 61. A recycling drive belt 65 is installed outside the upper recycling rotating wheel 63. A silicon carbide recycling box 66 is installed outside the recycling drive belt 65. A recycling rotating rod gear 67 is installed outside the recycling main body rotating rod 61.

[0030] The connection part between the recycling main body rotating rod 61 and the recycling rotating rod gear 67 is located inside the transmission bin 11. The outside of the recycling main body rotating rod 61 is in transmission connection with the 47 outside the second rotating rod 44 through the recycling rotating rod gear 67. The number of teeth on the outside of the recycling rotating rod gear 67 is more than the number of teeth on the outside of the recycling drive gear 47; When the second rotating rod 44 rotates, it can drive the recycling main body rotating rod 61 to rotate through the meshing connection between the recycling drive gear 47 and the recycling rotating rod gear 67. The difference in the number of teeth on the recycling drive gear 47 and the number of teeth on the recycling rotating rod gear 67 enables the second rotating rod 44 to rotate multiple times before driving the recycling main body rotating rod 61 to rotate one week. When the recycling main body rotating rod 61 rotates, it can drive the uniform feeding cylinder 62 and the upper recycling rotating wheel 63 to rotate. When the uniform feeding cylinder 62 rotates, it can uniformly feed the silicon carbide.

[0031] The outside of the upper recycling rotating wheel 63 is in transmission connection with the lower recycling rotating wheel 64 through the recycling drive belt 65. The silicon carbide recycling boxes 66 are evenly distributed outside the recycling drive belt 65; When the recycling main body rotating rod 61 drives the upper recycling rotating wheel 63 to rotate, it can drive the lower recycling rotating wheel 64 and the recycling drive belt 65 to rotate. When the recycling drive belt 65 rotates, it can drive the external silicon carbide recycling boxes 66 to move synchronously.

[0032] One side of the silicon carbide recycling box 66 that fits the recycling bin 12 is provided with an opening. One side of the silicon carbide recycling box 66 facing the rotation direction of the recycling drive belt 65 is provided with an opening; When the recycling drive belt 65 drives the silicon carbide recycling box 66 to move, the silicon carbide recycling box 66 can collect the larger-sized silicon carbide particles and drive them to rise.

[0033] One side of the silicon carbide filtering mechanism 9 close to the recycling bin 12 is lower than the side far from the recycling bin 12. Two openings and a collecting groove are arranged inside the recycling bin 12; The larger-sized silicon carbide on the silicon carbide filtering mechanism 9 can enter the interior of the collection trough on the recovery bin 12 through the opening at the lower part of the recovery bin 12, and the silicon carbide recovery box 66 can enter above the silicon carbide guide plate 8 through the opening at the upper part of the recovery bin 12 when driving the silicon carbide particles inside the collection trough to move upward.

[0034] When the second rotating rod 44 rotates, it can drive the main recovery rod 61 to rotate through the meshing of the external recovery drive gear 47 and the external recovery rod gear 67 on the main recovery rod 61. The number of teeth on the recovery rod gear 67 is more than that on the recovery drive gear 47, so that the recovery drive gear 47 can only drive the recovery rod gear 67 to rotate one week when rotating multiple weeks. When the main recovery rod 61 rotates, it can drive the uniform feeding cylinder 62 to rotate. When the uniform feeding cylinder 62 rotates, it can uniformly feed the silicon carbide guided by the silicon carbide guide plate 8 to prevent the silicon carbide from blocking the outlet at the bottom of the silicon carbide guide plate 8. And when the main recovery rod 61 rotates, it can also drive the upper recovery runner 63 to rotate. When the upper recovery runner 63 rotates, it can drive the lower recovery runner 64 to rotate through the recovery drive belt 65. When the recovery drive belt 65 rotates around the upper recovery runner 63 and the lower recovery runner 64, it can synchronously drive the silicon carbide recovery box 66 to rotate. When the pulverizing mechanism 4 pulverizes the silicon carbide, the incompletely pulverized or splashed silicon carbide particles enter the interior of the recovery bin 12 from the opening at the lower part of the recovery bin 12 under the filtering and guiding of the silicon carbide filtering mechanism 9. And when the recovery drive belt 65 drives the silicon carbide recovery box 66 to move, the silicon carbide recovery box 66 can collect the silicon carbide particles inside the collection trough and drive the silicon carbide particles to move when the silicon carbide recovery box 66 moves. When the silicon carbide recovery box 66 drives the silicon carbide particles to move upward, the silicon carbide particles inside the silicon carbide recovery mechanism 6 can enter above the silicon carbide guide plate 8 from the higher opening inside the recovery bin 12. After the silicon carbide particles enter above the silicon carbide guide plate 8, they can enter the pulverizing mechanism 4 again for secondary pulverization, thus significantly improving the pulverization quality of the silicon carbide particles.

[0035] Example 4: A production method for silicon carbide sand, using a pulverizing device as in Examples 1 to 3, includes the following steps: First, drive the pulverizing mechanism 4 to perform pulverizing operations through the drive mechanism 2; The silicon carbide filtering mechanism 9 can filter the incompletely pulverized silicon carbide sand and guide it into the interior of the recovery bin 12; When the pulverizing mechanism 4 performs pulverizing operations, it can also drive the silicon carbide recovery mechanism 6 to move the silicon carbide particles inside the recovery bin 12 to the silicon carbide guide plate 8; Driven by the crushing mechanism 4, the silicon carbide recycling mechanism 6 can not only recycle silicon carbide particles but also uniformly feed the silicon carbide particles during the recycling process; The crushed silicon carbide sand can be discharged through the discharge port 10.
